Keanekaragaman Makroalga di Sekitar Pantai Desa Fodo Kota Gunungsitoli

Abstract

The research of “Macroalgae Diversity at Beach Fodo Village, Gunungsitoli” has been done. The objectives of this research were to know the diversity of macroalgae and the correlation between physical-chemical factors and the diversity of macroalgae. The research was done by using Kuadratic Transect Methode and by determining 3 research stasions along the coastline. The sampling was done 25 times on each research station. The research found 3 kinds of macroalgae which consist of 7 classes, 8 families and 10 genera. The amound of the highest density 50,76 ind/m² was found on the station 3 and the lowest 13,16 ind/m² was found on the station 2. The highest diversity index 1,470 was at station 1 and lowest 1,018 was at station 2. The highest uniformity index 0,802 was at station 3 and the lowest 0,623 was at station 3. The correlation analysis result shows that salinity strongly correlate to the macroalgae diversity index (H’).
